Is this a drop in part for the 3.5 vq motor? Who makes these knock off cams?

Yes. You will need a head gasket set and head bolts, but this is complete.

I'm only interested in the cams only. I have an 03 Max and want to know two things. Are you willing to selling the cams alone? Will the cams bolt right on my car WITHOUT ANY modifications?

Heads are already prepped with the parts to accommodate the revs those cams are gonna want. Good price. I wouldn't separate if I was moncef
